Definitions

  • This invention relates to an electrical cable connector of the kind set forth in the introductory part of claim 1.
  • Cable connector assemblies are known in a wide variety of applications. In many of these applications, superior electrical contact between two cables is desired in addition to a more secure engagement mechanism. Further, it is desirable that the connectors be durable so as to withstand heavy and continuous use. It is also desirable that a connector assembly be versatile so as to be useful in more than one application. Economy of manufacture is still an additional consideration. Positive engagement is a primary concern. There should also be some indication of engagement or disengagement which is visual or by "feel".
  • the connector assembly according to the invention is characterised in claim 1.
  • a cable connector assembly comprises a first cable connector having a protruding connector post at one end adapted to fit a recess in a second cable connector.
  • one connector When coupled, one connector may be rotated 180° about the longitudinal axis of the assembly so as to engage the connectors. In order to disengage the connectors, the 180° rotation is performed in the reverse direction.
  • This engagement/disengagement feature is provided by an internal cam-type mechanism.
  • the connector assembly includes external visual indicia as to its engaged or disengaged state.
  • Each substantially cylindrical connector is provided with two opposing, differing symbols, such as a circle and a square, at the mating end thereof.
  • a circle will be adjacent a circle and a square adjacent a square; correspondingly, when engaged (i.e. after 180° twist), each circle will be adjacent each square, since the symbols are on diametrically opposing sides of the connector.
  • the connector post on the first connector may be provided with an asymmetric longitudinal groove extending through the post in order to reduce wear and ensure a more secure fit.
  • first and second cable connectors 12 and 14 join lengths of electrical cable 16 and 16 ⁇ .
  • Both generally elongated connector bodies are comprised of connector blocks 48 and 50 of electrically conductive material such as brass which are substantially encased in insulating material 18.
  • Protruding at one end from first cable connector 12 is a generally cylindrical, conductive connector post 20 having a free end 22 and a fixed end 24.
  • the connector post is adapted to fit into generally cylindrical recess 26 at the coupling end 27 of second connector 14.
  • connector post 20 is provided with an asymmetric annular groove 34 which correspondingly defines a substantially annular ridge 36 at the free end of the post.
  • Ridge 36 includes a flat section 40 which is key to the camming mechanism. It also includes an inner cam surface 41 which interacts with wedge 38 which protrudes radially inwardly from the interior of recess 26 so as to provide a "pull up" action between the connectors 12, 14.
  • the resilient outer casings of the connectors will be compressed at the annular area of their contact 43. This is permitted because the connector blocks, one of which is shown at 48, are normally recessed from this outermost area of contact 43.
  • cam means 28 prevents inadvertent disengagement of connectors after coupling.
  • Asymmetric annular groove 34 is dimensioned and posi­tioned so as to prevent rotation of either connector through an angle of greater than about 180°.
  • Connectors 18, 20 may be made of rubber or other electrically insulating material.
  • connector post 20 is provided with a longitudinal groove 44 which extends through the post from face 46 to connector block 50.
  • the groove is preferably asymmetric, as illustrated in Figure 8.
  • This aspect of the invention provides a linear spring action in the connector post structure, and thus ensures a more secure fit, improved electrical contact between the two connectors, and reduced wear with prolonged use. Addi­tional rotational resistance and greater "break away" torquest are also provided.
  • Figures 2 and 5 illustrate the use of optional external visual indicia with the present invention.
  • First connector 12 may at its mating end be provided with two different symbols 30 and 32, shown here as a circle and a square, placed diametrically opposed positions on the connector.
  • second connector 14 is provided with corresponding symbols 30 ⁇ and 32 ⁇ (not shown).
  • a circle is adjacent a circle, as shown in Figure 2
  • a square is adjacent a square.
